Re: slurpd from 1.2 to 2.1

[pturgyan@umich.edu]

We ran into the same problem when moving from openldap 1.2 to openldap 2.1.
The problem is that slurpd is doing v3 ldap protocol to the replicas.

We patched slurpd to parse a new "version" configuration argument
in the replica statement.  If the version is set to 2,  then slurpd
talks v2 protocol to the replica.  Note that the v3 operatonal attributes
don't need to be replicated to a v2 server.

Here is an example replica line:

replica         host=v2.slapd.umich.edu bindmethod=simple "binddn=cn=v2replication,dc=umich,dc=edu" credentials=v2too version=2 attr!=structuralObjectClass,entryUUID,entryCSN,subschemaSubentry,hasSubordinates

Here's the patch:
